Hi,
I was recently studying the intricate world of the GNU
autoconf tool when I stumbled across an anomaly.
The GNU ppl (i.e., Linux) are known to install everything
on /usr/. Therefore, the autoconf tool checks there. To have it
check elsewhere, e.g., /usr/local/ (our ${LOCALBASE}); we "trick"
it by defining either/both CFLAGS and CXXFLAGS. For instance,
CONFIGURE_ENV= CFLAGS="${CFLAGS} -I${LOCALBASE}/include -L${LOCALBASE}/lib"
\
CXXFLAGS="${CXXFLAGS} -I${LOCALBASE}/include -L${LOCALBASE}/lib"
The trick works usually wonderfully for AC_CHECK_LIB but
does not do the voodoo for AC_CHECK_HEADERS.
For example, the following:
dnl Just something to keep autoconf from annoying me
AC_INIT(something.in)
dnl Checks for programs.
AC_PROG_CC
AC_PROG_INSTALL
dnl Checks for libraries.
AC_CHECK_LIB(guile, gh_procedure_p)
dnl Checks for header files.
AC_CHECK_HEADERS(libguile.h)
AC_CHECK_HEADER(guile/gh.h)
I have
-rw-r--r-- 1 root wheel 781424 Jan 4 13:52 /usr/local/lib/libguile.a
lrwxr-xr-x 1 root wheel 13 Jan 4 13:52 /usr/local/lib/libguile.so -> libguile.so.9
-rwxr-xr-x 1 root wheel 596400 Jan 4 13:52 /usr/local/lib/libguile.so.9
-r--r--r-- 1 root wheel 4598 Jan 4 13:52 /usr/local/include/libguile.h
However, I get the following annoying output after
autoconf(ing) it:
creating cache ./config.cache
checking for gcc... cc
checking whether the C compiler (cc -O -pipe -I/usr/local/include -L/usr/local/lib ) works... yes
checking whether the C compiler (cc -O -pipe -I/usr/local/include -L/usr/local/lib ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether cc accepts -g... yes
checking for a BSD compatible install... /usr/bin/install -c -o root -g wheel
checking for gh_procedure_p in -lguile... no
checking how to run the C preprocessor... cc -E
checking for libguile.h... no
checking for guile/gh.h... no
Ideas? Why is the LIB check failing on this one, I was
confident it would work. As per the HEADER, I was already expecting
the failure but how do I get it to work?
This particular example is incidental to an update to the
mail/icqmail port I am reviewing.
All help appreciated. I am wondering why do I have the feeling
I am gonna hate this. :)
